  • Patent number: 4120438
    Abstract: An apparatus for driving a nail into a relatively inaccessible surface. The nail driver includes an elongated cylindrical housing having a bore extending between its front and rear ends, the rear end covered by an end cap. A rigid rod of lesser diameter than the bore of the housing is slidably received in the bore, with the rear end of the rod projecting rearwardly through the end cap when the front end of the rod is adjacent the front end of the housing. The rear end of the rod carries a weighted handle. The front end of the rod includes a magnetized end portion of about the same diameter as the bore of the housing. A first compression spring extends between the end cap and the weighted handle to absorb the momentum of the weighted handle at the forward end of a stroke, and a second compression spring surrounds the rod within the housing and extends between the end cap and the end portion of the rod for resiliently biasing the rod in a forward direction.
